ELECTROPHOTOGRAPHIC MEMBER, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC APPARATUS
Abstract:
The electrophotographic member includes an electroconductive substrate and an electroconductive surface layer. The surface layer contains an electroconductivity imparting agent and a polyrotaxane including a first and a second polyrotaxane molecule.The first polyrotaxane molecule includes a first cyclic molecule, and the second polyrotaxane molecule includes a second cyclic molecule. The cyclic molecules of the first and the second polyrotaxane molecules are bound in such a manner that the oxygen atom of a hydroxy group of the first cyclic molecule and the oxygen atom of a hydroxy group of the second cyclic molecule are bound with a structure represented by the following structural formula (1): *-R1-Z-R2-** In this formula, z represents a linking group, and signs “*” and “**” represent binding sites to be bound to either of the oxygen atoms derived from the hydroxy groups of the first and the second cyclic molecule. R1 and R2 each represent a specific structure.
